Application filed September 29, 1925. serial No. 59,284.

My invention relates to a heating device and has particular reference toastove using a gaseous fuel, the principal object of the inventionbeingto provide a simple, economical and efficient stove in which thecombusarea to be heated to uniform temperature,

and to varying degrees of temperature. without coldor hot zones;. toprovide a heater which is entirely air insulated, and hence may withperfect safety be placed in walls I and to provide a heater by whichpure fresh air may be delivered into and circulated about a room orother enclosure, and. heated to a degree that'will provide a comfortableatmosphere without impairingthe vitality of the pure air byoverheatingand drying;

mounting the fines 1n this manner, serv ng-to Other objects will appearfrom the-followingl specification'in connection with the accompanyingdrawing, which illustrates a preferred embodiment of the invention, andin which I 3 Fig. 1 is a front view partly broken showing my invention.

Fig. 2 is aside view partly in section, the

' section taken approximately on line -2.2.

Fig. 1, and I Fig. 3 is a sectional: plan view on line 3-3 Fig. 1.

My'invention is forms in which it may be carried into practical effectand as comprising in a general sense astructure having a communicationwith the atmosphere, for leading into a closed area the outside air, andanother communication with the atmosphere' for continuously carrying outthe air from the closed area, with ameans for heating the introducedatmospheric 1 air.

In a more specific sense, the invention as shown in the preferred mannerof construc tion, comprises acasing 1 formed with sides 2, back '3, andtop 4 and which-1s open at the front and bottom. The sides 2, at] thebottom thereof are formed into or pro-,

vided with ducts or passageways 5, which .efliciently absorbs theheat'ofthe fines on shown in one of many communicate in any desirablemanner with the atmosphere outside anenclosed areaor space. 1 Theseducts 5 extend the full-depth of the sides 2 and are of limited heightand width, and serve to convey the atmospheric air from 'the;bottom intoa-room or other area, as will appear later. To therear or back- 3 of thecasing andbetween the, ducts .5, is fastened in any desirable'fmanner, a

partition 6, constitutinga stack, extending vertically through said case1 and at the bot tom being in open communication withthe closed areatobe heated or'ventilated, the, partition 6, for this purposeterminating,'a short distancefromthe bottom, and providing a freeentrance of the used heated air into said stack.

The upperarea of the stackftl is enlarged,

as seen: at 6, and extends abovethetop of the casing 1, andto: the wall?of, said-stack enlargement'are connected the elbows 8 of Y aplurality ofspaced lines 9, thefelbows'flS i being, as seen, n communication withsaid, stack. These elbows 8 are connected to the wall 7, at a shortdistance from the top 4 ofthecasing 1, the space-A created by I permitthe incoming air to pass over the; top of the fines. The flues 9, asseen, are also spaced from each other, from the side walls 2 and fromthe back 3 of the casing l, and being thus entirely freely suspendedwithin 1 the'casing, the incoming cold air readily and all sides andtravels into the room inhe'ated condition, the temperature dependingupon the heat in thecombustion chamber 10. The flues' 9 are conjoinedwith the combustion' chamber 10, in which is disposed a burner ,11,connected with a source of fuel/supply,

not shown. The-top of said'combustion chamber is provided with"openings11"'- flues .9. These openings are considerably 'throughwhich the heatof combustion es- I capes from thecombustion chamber into .the

smaller than the flue openingsandare thus desigm'ed to retard the flow.of the heat of combustion and thereby insure the fullest-ex'e pansion ofsamewithinthe flues. As shown, the combustion chamber' lO is carried,or' supported by the flues 9. any suitable connection being used forthis. purpose, such for instance as that illustrated in Fig. 1. i-

and comprising an upstanding collar 12fon Y th 3 f 'th combustionchambercto which the flues '9 are fastened bybolts or other means. Theconstruction, of suspendng'the fines and the combustlon chamber providesa cold air space entirelyaround these parts and between them and the.cas

ing', and automatically insulates them from the casing;

heat in the combustion chamber 10, the air space between the casing andfines, and-between the fines efficiently insulates the casing from theheat, which is absorbed bythecold air entering from the bottom. Specialinsulati'on, as covers, blocks or sheets of asbestos,

' for other the proof materials are thus rendered wholly unnecessary,and a heater of this type may safely-be placed and concealed in thewalls of a building.

Below theburner 11, in the combustion chamber 10, I preferto place abaffle plate 12' which is suitably supported above the bottom 13 of thecombustion chamber, and which serves to deflect the air entering thecombustion chamber 10 through ports 14in the bottom 13, around theburner, and thereby prevent roaring, which would otherwise occur.'Beneath'the combustion chamber 10 I prefer to placea means forpreventingv the transfer of heat from the combustion chamber tothebottom and for confining the heat,

and directing also the incoming cold air about the combustion chamber.This"means maybe in' the'form ofa plate 15, extending longitudinally ofand under the combustion "anjupstanding portion 15 extending in front edinto the ports chamber 1'0, and supported upon the walls of'the ducts'5'. The plate 15 is formed with of and for thefull width of'the'combustion chamber 10, this upstanding portion co-op- *erating with theplate 15 for the purposes dealso for causing a part ofthe scribed, andincoming cold air to bedeflected and divert- 14 in the bottom of thecombustion chamber.

7 From the construction as outlined,.it will be observed thatatmospheric air enters through the side ducts 5 and travels upwardly inthe space "B (Fig. 1), between the .side walls 2, the combustion chamber10 and the flues 9, and also behind the fines.

To prevent the immediate ingress of the outside air through the ducts5into the area to be heated, and direct it into immediate contact withthe flues or into the area behind between the flues,

the fines to necessitate it passing between and being heated by saidfines, I prefer to provide'a cover'16, formedto fit over the'fr'ont ofthe casinglp'and provided with side panels 17" which elose'the spaces Bbetween the'side walls 2 and the combustion chamber 10 and fines 9 todivert the incoming air to This cover 16 is also provided with an upperhorizontal panel 18,

which extends below the top of the casing 11 and slightly above thetopof the'flues 9 to retard the air fiowand heat same and withTherefore, regardless of the 7 directly into ways pure and fresh. notdesired, the stove herein described acts 'heatingmeans within saidcasing a lower horizontal panel 19, which serves to confine the areaabout the combustion chamber 10, and is disposed above the bottom toprovide and permit free passage-of the air. These panelsil'i, 18 and 19,also serve to support a wire or other mesh 20 of any configuration andare preferably designed to provide an ornate enclosure, which inaddition to performing the functions re- 7 around-and between the fines9,'-passes into the-room or other area and" displaces the colder airtherein, the displaced air, which is the lower stratum, being forced anddrawn out of the area through the stack 6, which is at the bottom indirect and open communication 5 with the area to be heated. The

energy with which the cold air or the used air is forced and drawn outfrom the closed space is augmented by the hot combustion gases whichescaping from. the fiues 9, enter the stack 6, above thepoint ofcommunication ofsame with the'closed area. In'this wise, the air in'aroom or other enclosure iscontinuously"displaced, without creatingnoticeable and objectionable drafts.

A moderate, comfortable temperature may bemaintained' at all times, andthe air. 18 al- VVhen. heated air is as a ventilator, permitting acontinuous inflow of fresh air and an uninterrupted out-.

flow of the used air withoutthe necessity of opening windows or otheroutlets that develop drafts and induce undesirable air current with theaccompaniment of. dust and other objectionable matter.
